Low Temperature Melting Point Frit Glass Powder

Product Overview

Low melting point glass powder is an advanced sealing material introduced by ANYWHERE POWDER researchers, which has a low melting temperature and sealing temperature, good heat resistance and chemical stability, high mechanical strength, and is widely used in vacuum and microelectronics technology, laser and infrared technology, high energy physics, energy, aerospace, automotive and many other fields. It enables sealing between glass, ceramic, metal and semiconductor. As a new material, low melting point glass powder has been used in some new materials, but the application prospects are far beyond the current encounter, and still need to be explored and expanded by researchers.

• Low melting point glass powder has different names in different application fields.
• In the field of flame-retardant rubber and plastic, known as: Ceramic powder.
• In the field of sintered materials for precision device, known as: Inorganic solder/Soldering-flux.
• In the field of industrial catalyst, high-temperature flux, known as: Inorganic solvent.
• In the field of high-temperature ink and low-temperature ceramic color glaze, known as: Inorganic ink.
• In the field of bonding material for special optical instrument and metal precision instrument, known as: Inorganic sealant.
